Principle

Infrared measurement technology:

Polar gas molecules absorb specific wavelengths of infrared light and have unique spectral absorption characteristics. The infrared light emitted from the infrared light source is modulated and passed through the non-absorbing reference chamber and the absorbed sample chamber respectively, and reaches the detector. The concentration of the measured gas is obtained according to the difference of different energy signals received by the detector. High measurement accuracy, good stability, fast response, low background gas interference.

 

Ion flow oxygen technology:

Oxygen molecules in the measured environment diffuse through the diffusion holes to the negative electrode and flow from the negative electrode through the electrolyte oxygen pump to the positive electrode under the action of the electric field, and then return from the positive electrode to the measured environment. The current flowing through the loop has a corresponding ion current value under different oxygen concentration, there is a function relationship between the ion current value and the oxygen concentration in the measured gas. High resolution, good stability, small drift, low power consumption.
